does playing roulette with a system actually change your edge

I've heard all kinds of stories about people using systems like Martingale, Labouchere, you name it, claiming they can beat the wheel if they just stick to their plan. I tried a couple of them myself when I first started, even tracked results for a few months. Never really noticed any long-term change to my bottom line, just different rollercoasters. Feels like it's still just 50-50 shot with red/black or even/odd, minus the house edge.

Curious if anyone here has actually managed a real win streak with a system or if it's just another way to pace your losing sessions. Any experiences worth sharing?
